Both Busch (Daytona) and Gordon (Atlanta) had hard collisions with concrete walls unprotected by a SAFER barrier.

A third driver, Erik Jones, later collided with an unprotected wall in last Saturday’s XFINITY Series race at Las Vegas Motor Speedway.

While Gordon and Jones were uninjured in their respective incidents, Busch suffered a compound fracture of his lower-right leg and a mid-foot fracture when his No. 54 Toyota barrelled head-first into an unprotected wall in the XFINITY season opener at Daytona on Feb. 21. He has not raced since.
